From WhatsApp Cantonese to Professional English: Cleaning Up Your Client Messages

You're chatting with a client on WhatsApp. It's quick, casual, efficient. You type in a mix of Cantonese, English, and abbreviations:

"Hi! 上次個proposal ok啦，但budget有啲tight，可唔可以減少少scope? Thx!"

Your client replies. You go back and forth. Everything's fine.

Then your boss says: "Can you send a proper email summarizing what you discussed?"

Suddenly, you're stuck. You stare at your WhatsApp chat history and think:

• "How do I turn this into a professional email?"
• "Do I translate word-by-word or rewrite everything?"
• "What if it sounds too casual? Too stiff?"
• "How do I keep the tone friendly but still professional?"

Twenty minutes later, you're still rewriting the opening sentence.

Sound familiar?

If you're a Hong Kong professional who chats with clients in Cantonese-English mix on WhatsApp but needs to send formal emails, this guide is for you.

Why WhatsApp Tone Doesn't Work in Email

WhatsApp and email serve different purposes—and require different communication styles.

When you copy-paste WhatsApp messages into an email—or try to translate them directly—you end up with something that sounds:

• Too casual ("ok啦" → "it's ok lah")
• Too fragmented (three short messages → three disconnected sentences)
• Too vague ("減少少scope" → "reduce scope a bit")
• Too mixed (Cantonese + English = confusing for non-Cantonese speakers)

The result? Your email sounds unprofessional, unclear, or even disrespectful—even though your WhatsApp chat was perfectly fine.

This is why Cantonese speakers struggle with English emails at work. We're not bad at English—we're just trying to apply WhatsApp communication rules to a format that doesn't share them.

The Problem: Three Common WhatsApp-to-Email Scenarios

Let's look at three real examples of messy WhatsApp messages and how to convert them into professional emails.

---

Scenario 1: Negotiating Budget and Scope

WhatsApp chat history:

You: Hi! 上次個proposal睇咗未？
Client: 睇咗，overall ok
You: Great! 咁我哋下個禮拜開始？
Client: Budget有啲tight，可唔可以減少少scope?
You: Ok啦，我諗吓點改，之後send個updated version俾你
Client: Thx!

Your first attempt at email (直譯):

Hi [Name],

Last time's proposal, have you seen it? You said overall ok. So we start next week? But you said budget is a bit tight, can we reduce scope a bit? Ok, I'll think about how to change it and send you an updated version later. Thanks!

Why it fails:

• Too conversational ("have you seen it?" "You said" "So we start?")
• Too fragmented (reads like separate WhatsApp messages, not a cohesive email)
• Too vague ("a bit tight" "reduce a bit" "think about how to change")
• Unclear structure (no clear opening, body, or closing)

Professional email version:

Subject: Updated Proposal – Adjusted Scope and Budget

Hi [Name],

Thank you for reviewing the proposal. I'm glad to hear that the overall direction aligns with your needs.

I understand that the budget is tighter than anticipated. To accommodate this, I've revised the scope to focus on the core deliverables while maintaining the quality you expect. The updated proposal includes:

• [Deliverable 1]
• [Deliverable 2]
• [Deliverable 3 – reduced scope]

The revised budget is [amount], which represents a [X]% reduction from the original proposal.

Please review the attached updated proposal and let me know if this works for you. If you'd like to discuss further adjustments, I'm happy to schedule a call.

Looking forward to your feedback.

Best regards,
[Your Name]

What changed:

• Opening: Acknowledges the previous conversation professionally
• Body: Clearly explains the situation and proposed solution
• Structure: Uses bullet points for clarity
• Tone: Friendly but professional ("I'm glad to hear" "I understand" "I'm happy to")
• Closing: Clear next steps and call-to-action

---

Scenario 2: Chasing a Delayed Response

WhatsApp chat history:

You: Hi! 上個禮拜send咗個report俾你，睇咗未？
You: 如果有問題可以話我知
You: 我哋要confirm先可以繼續做
(No response for 3 days)
You: Hi, 有冇收到我嘅message?

Your first attempt at email (直譯):

Hi [Name],

Last week I sent you a report, have you seen it? If there are problems you can tell me. We need to confirm before we can continue. Did you receive my messages?

Why it fails:

• Sounds passive-aggressive ("Did you receive my messages?")
• Too direct ("We need to confirm before we can continue" sounds demanding)
• No context (doesn't remind them what the report was about)
• Fragmented (reads like four separate WhatsApp messages)

Professional email version:

Subject: Follow-up: [Report Name] – Awaiting Your Feedback

Hi [Name],

I hope this email finds you well. I wanted to follow up on the [report name] I sent on [date]. I understand you're likely very busy, so I thought I'd check in to see if you had a chance to review it.

The report covers [brief summary of key points], and we're ready to proceed with the next phase once we receive your feedback. If you have any questions or need clarification on any section, please don't hesitate to reach out.

If it would be helpful, I'm happy to schedule a brief call to walk through the findings together.

Thank you for your time, and I look forward to hearing from you when you have a moment.

Best regards,
[Your Name]

What changed:

• Opening: Polite and acknowledges they're busy ("I hope this email finds you well" "I understand you're likely very busy")
• Context: Reminds them what the report was about
• Tone: Respectful, not demanding ("when you have a moment" instead of "we need to confirm")
• Offer to help: Shows willingness to make it easier for them ("happy to schedule a call")

Scenario 3: Pushing Back on an Unrealistic Request

WhatsApp chat history:

Client: Hi, 可唔可以今日5點前send個final version俾我？
You: 今日5點？😅
You: 有啲趕喎
You: 我哋仲有好多要改
You: 聽日得唔得？
Client: 我今晚要present
You: 咁我盡量啦，但唔保證quality

Your first attempt at email (直譯):

Hi [Name],

You asked if we can send the final version by 5pm today? That's a bit rushed. We still have a lot to change. Can we do it tomorrow? You said you need to present tonight. I'll try my best but I can't guarantee quality.

Why it fails:

• Sounds defensive ("That's a bit rushed" "We still have a lot to change")
• Too blunt ("I can't guarantee quality" sounds like you're not trying)
• No solution offered (just pushes back without alternatives)
• Fragmented (reads like separate WhatsApp messages)

Professional email version:

Subject: Re: Final Version Timeline

Hi [Name],

Thank you for the update on your presentation timeline. I understand the urgency.

To deliver the quality you expect, we'd need until tomorrow morning to complete the final revisions. However, if you need something for tonight's presentation, we can provide a near-final draft by 5pm today, with the polished version to follow tomorrow.

The draft will include all major content and structure, though some formatting and final edits will still be in progress.

Please let me know which option works better for you, and we'll prioritize accordingly.

Best regards,
[Your Name]

What changed:

• Opening: Acknowledges their urgency ("I understand the urgency")
• Solution-focused: Offers two options instead of just saying no
• Professional tone: Explains the trade-off without sounding defensive
• Clear next steps: Asks them to choose and commits to delivering

The 4-Step Process: WhatsApp Chat → Professional Email

Here's a systematic approach to convert any WhatsApp conversation into a professional email:

Step 1: Extract the Key Information

Read through your WhatsApp chat and identify:

• What was discussed? (main topic)
• What was agreed? (decisions, commitments)
• What's needed next? (action items, deadlines)
• What's the tone? (friendly, urgent, apologetic, etc.)

Example (from Scenario 1):

• Topic: Budget and scope adjustment
• Agreed: Client likes the proposal but needs lower budget
• Next: You'll send an updated proposal with reduced scope
• Tone: Collaborative, solution-focused

---

Step 2: Organize into Email Structure

Structure your email with these sections:

1. Subject line: Clear and specific (e.g., "Updated Proposal – Adjusted Scope and Budget")
2. Opening: Acknowledge the previous conversation (e.g., "Thank you for reviewing the proposal")
3. Body: Explain the situation and proposed solution (use bullet points for clarity)
4. Closing: Clear next steps and call-to-action (e.g., "Please review and let me know")
5. Sign-off: Professional closing (e.g., "Best regards")

---

Step 3: Translate Tone, Not Just Words

Don't translate Cantonese phrases word-by-word. Instead, translate the intent and tone:

If you've ever wondered which Cantonese phrases don't translate well, this is why. Translation isn't just about words—it's about bridging two completely different communication styles.

---

Step 4: Polish for Professionalism

Before sending, check:

• Is the tone appropriate? (friendly but professional, not too casual or too stiff)
• Is the structure clear? (opening, body, closing)
• Are next steps explicit? (what you'll do, what they need to do, by when)
• Is it free of Cantonese-English mix? (no「ok啦」or「thx」)
• Does it sound confident? (not defensive, not over-apologizing)

Common Mistakes to Avoid

❌ Mistake 1: Copy-Pasting WhatsApp Messages

Bad:

Hi [Name],

上次個proposal ok啦，但budget有啲tight，可唔可以減少少scope? Thx!

Why it fails:
Mixed language, too casual, unclear structure.

Better:
Rewrite in full English with professional structure (see Scenario 1 example above).

---

❌ Mistake 2: Translating Word-by-Word

Bad:

Hi [Name],

Last time's proposal is ok lah, but budget has a bit tight, can or not reduce a bit scope? Thanks!

Why it fails:
Sounds awkward and unprofessional ("ok lah" "has a bit tight" "can or not").

Better:
Translate the intent, not the words: "Thank you for reviewing the proposal. I understand the budget is tighter than anticipated. To accommodate this, I've revised the scope..."

---

❌ Mistake 3: Being Too Casual

Bad:

Hey! So about that thing we talked about on WhatsApp... can we do it tomorrow instead? Lol sorry 😅

Why it fails:
Too informal for professional email ("Hey" "that thing" "Lol" emojis).

Better:
"Thank you for the update. To deliver the quality you expect, we'd need until tomorrow morning to complete the final revisions. Please let me know if this timeline works for you."

---

❌ Mistake 4: Over-Explaining

Bad:

Hi [Name],

I saw your message on WhatsApp yesterday at 3pm, and then you sent another message at 4pm, and then this morning you sent another one, so I'm writing this email to respond to all of them...

Why it fails:
Too much unnecessary detail. Just get to the point.

Better:
"Thank you for your messages. I wanted to follow up on [topic] and provide an update..."

When WhatsApp is Actually Better

Not every client communication needs to be a formal email. Here's when to use each:
